共建共治共享是当代社会治理制度建设的根本性命题，在基层社区中表现为多元主体的协同治理。随着社会主要矛盾的转变，公众的利益诉求呈现多元化趋势，成为构建基层社会治理共同体的主要挑战。这种多元的利益诉求冲突在城市老旧社区更新改造中尤为凸显。本文选取老旧社区改造作为研究社区治理共同体的透镜，借助协同治理理论构建了过程分析框架，对老旧社区改造的典型案例展开过程追踪，分析了多元利益诉求中基层社区协同治理的阶段性特征，提出了实现老旧社区协同改造的路径建议，并对案例研究中的主要发现进行了理论和实践意义层面的讨论。

       在社区改造的初始状态，存在治理碎片化、资源分散、诉求多元、利益冲突等多重不利因素，阻碍老旧社区进入协同改造进程。为此，本文提出多要素复合的协同治理过程分析框架，包括初始条件、阶段性成果、持续性投入三部分，在实证研究中重点关注了作为外部要素的资源与制度和作为内部要素的需求与情感的动态变化过程。协同改造历经了社会动员、成果转化、集体行动三个阶段，不同阶段展现出基层协同治理中不同的目标任务和关键行动，在典型案例分析的基础上梳理了实现老旧社区协同改造的路径建议。未来的老旧社区协同治理实践，建议从培育协同愿景、优化协同机制、增强协同联系、提升协同动能、巩固协同成果等方面出发，通过深化党建引领、消解诉求冲突、善用跨边界者、强化互信互通、助推合作再生等具体方式，助力老旧社区协同开展更新改造，并为基层社区的可持续发展提供可行路径。

       与已有的社区治理和共同体研究相比，本研究更加注重协同治理的过程，清晰地呈现了协同治理不同阶段的主要挑战、目标任务和行动策略，为基层行动主体提供更加具体的行动指南。同时，本研究从两个方面丰富了现有的社区治理研究，一是采用了动态分析的过程视角，将基层治理共同体研究从“快照”延伸为“影像”，丰富了基层治理共同体形成的细节和行动策略；二是选取老旧社区改造这一极具利益诉求冲突的治理问题展开研究，对社会动员、共识达成、资源整合等治理目标具有广泛的迁移价值。

       Building and sharing together is a fundamental proposition for the construction of contemporary social governance systems, which is manifested in primary-level communities as the collaborative governance of multiple actors. With the transformation of the main contradiction in society, the public's interests have shown a trend of diversification, which has become the main challenge of building primary-level social governance communities. This diverse conflict of interests is especially prominent in the renewal and transformation of old urban communities. In this paper, we select the renovation of old communities as a lens to study the community of community governance, construct a process analysis framework with the help of collaborative governance theory, carry out process tracing on the typical cases of old communities' renovation, analyze the stage characteristics of primary-level community collaborative governance in the pluralistic interests, put forward the path suggestions to realize the collaborative renovation of old communities, and discuss the theoretical and practical significance of the main findings in the case study. The main findings of the case study are discussed at the level of theoretical and practical significance.

       In the initial state of community transformation, there are multiple unfavorable factors, such as governance fragmentation, resource dispersion, multiple demands, and conflict of interests, which impede older communities from entering the collaborative transformation process. For this reason, this paper proposes a multi-factor composite analytical framework of collaborative governance process, including three parts, namely, initial conditions, phased outcomes, and continuous inputs, and focuses on the dynamic change process of resources and systems as external factors and demands and emotions as internal factors in the empirical study. The collaborative transformation has gone through three stages of social mobilization, outcome transformation, and collective action, and the different stages show different target tasks and key actions in grassroots collaborative governance, and the path suggestions for realizing the collaborative transformation of old communities are sorted out on the basis of typical case analysis. In the future practice of collaborative governance in old communities, it is suggested that we start from cultivating a collaborative vision, optimizing collaborative mechanisms, enhancing collaborative links, improving collaborative dynamics and consolidating collaborative achievements, and help old communities carry out collaborative renewal and renovation by deepening the leadership of party building, resolving conflicting demands, making good use of cross-boundary people, strengthening mutual trust and communication, and promoting cooperative regeneration, and provide a feasible path to the sustainable development of grass-roots communities. It also provides a feasible path for the sustainable development of primary-level communities.

       Compared with existing studies on community governance and community, this study focuses more on the process of collaborative governance, clearly presents the main challenges, goals and tasks, and action strategies at different stages of collaborative governance, and provides more specific action guidelines for primary-level actors. At the same time, this study enriches the existing research on community governance from two aspects: first, it adopts the process perspective of dynamic analysis, which extends the research on primary-level governance community from “snapshots” to “images” and enriches the details of the formation of the primary-level governance community and its action strategies; second, it selects an old community to study the process of collaborative governance, and then it selects an old community to study the process of collaborative governance. Secondly, it selects the old community transformation as a governance issue with conflicting interests for research, which has a wide range of transferable values for governance objectives such as social mobilization, consensus building and resource integration.
